为了能清楚地了解杀伤爆破战斗部爆炸预制破片和冲击波对雷达天线阵面靶板的复合毁伤特性，采用LS-DYNA3D动力有限元软件，对破片和冲击波在不同时序下对天线阵面等效靶板的复合毁伤作用过程进行了一系列数值模拟研究，描述了两者在不同时序下对靶板的复合毁伤过程中的基本现象，分析了靶板某典型节点的位移变化规律，揭示了破片和冲击波作用靶板的不同时序对靶板损伤变形的影响。研究表明：破片和冲击波对装备部件的复合毁伤效应，不是二者毁伤效应的简单叠加，而存在特殊的作用机理，且这与二者到达目标的时序有关。所得结果不仅促进了损伤机理的研究与发展，而且还对杀伤爆破战斗部结构的优化具有参考价值。

In order to understand the characteristics of multiplex damages of the fragment and shock wave to the radar antenna array plate,a series of numerical simulation of the process of fragment and shock wave damage target is done by the finite element code LS-DYNA 3D. The basic phenomena of multiplex damages is described detailedly,the variation regularity of plate node displacement is analyzed. The multiplex damages complexion of equipment caused by fragment and shock wave in different time sequence is obtained. The research indicates that equipment multiplex damages effect under fragment and shock wave is not the simple add two damage effect,but have the special action mechanism which is related to the time sequence of them. The results are helpful to study and perfect the damage mechanism and have reference value for the structure optimization of the blast fragmentation warhead.
